Abstract

This work provides an approach for simplifying and teaching of the confusing topic of Polarisation of light and relating Malus’s Law. Teaching Polarisation and the Malus’s Law are modestly achieved by means of smartphones with a convenient light meter application. The apparatus is designed so that the polarizer, the analyser, the laser light source and the smartphone are precisely aligned on a rail. During the performance, the angle of the analyser is basically varied with respect to the polariser and the transmitted light intensity is measured by the light meter application. The results clearly show that the transmitted light intensity is directly proportional to the squared polarization angle. The approach surely provides accessibility for physics teachers and would help students to learn and internalize Polarisation and relating Malus’s Law in a better manner.

Abstract

A set up of optical illusion based on 4f system and characterization of cloaking area have been carried out. The cloaking area is an area where the object is placed on the area as if it disappears from view; the set-up of cloaking area is located at the top of the third lens. The distance between the lens and the cloaking, which is generated from 4f system, depends on the size of the focal point and the size of the lens used. The larger the focal point of the lens used the wider the distance between the lenses and the larger the size of the diameter of the lens, the cloaking range will be increasingly wide, and vice versa. From the experimental results that we obtained that the cloaking area for set up using FL (focusing lens) 100, 50, 50 and 100 mm with a diameter of 3.6 cm lens is ± 2 cm, whereas for the set up using lens FL 150, 100, 100 and 150 mm with lens diameter 2.54 cm is ± 1 cm.

Abstract

A copper phthalocyanine (CuPc) thin film based gas sensor with FET structure and channel length 100 ?m has been prepared by VE method and lithography technique to detect NH3, motor cycle exhaust gases and CO. CuPc material layer was deposited on SiO2 by the vacuum evaporator (VE) method at room temperature and pressure of 8 x10-4 Pa. The stages of manufacturing gas sensor were Si/SiO2 substrate blenching with ethanol in an ultrasonic cleaner, source, and drain electrodes deposition on the substrate by using a vacuum evaporator, thin film deposition between the source/drain and gate deposition. The sensor response times to NH3, motorcycle exhaust gases and CO were 75 s, 135 s, and 150, respectively. The recovery times were 90 s, 150 s and 225, respectively. It is concluded that the CuPc thin film-based gas sensor with FET structure is the best sensor to detect the NH3 gas.Sensor gas berbasis film tipis copper phthalocyanine (CuPc) berstruktur FET dengan panjang channel 100 ?m telah dibuatdengan metode VE dan teknik lithography untuk mendeteksi NH3 gas buang kendaraan bermotor dan CO. Lapisan bahan CuPc dideposisikan pada permukaan silikon dioksida (SiO2) dengan metode vacuum evaporator (VE) pada temperatur ruang dengan tekanan 8 x10-4 Pa. Tahapan pembuatan sensor gas adalah pencucian substrat Si/SiO2 dengan etanol dalam ultrasonic cleaner, deposisi elektroda source dan drain di atas substrat dengan metode vacuum evaporator, deposisi film tipis diantara source/drain dan deposisi gate. Waktu tanggap sensor terhadap NH3, gas buang kendaraan bermotor dan CO berturut-turut adalah 75 s, 135 s,dan 150 s. Waktu pemulihan berturut-turut adalah 90 s, 150 s,dan 225 s. Disimpulkan bahwa sensor gas berstruktur FET berbasis film tipis CuPc merupakan sensor paling baik untuk mendeteksi adanya gas NH3.

Abstract

This study is aimed to compare the understanding of the concepts of secondary school students (junior and senior high school) and pre-service physics teachers in direct current electric circuits. This research was survey research using the quantitative descriptive method. The results showed that there were no significant difference among the junior high school, senior high school, and pre-service physics teacher students with the categories classified as sufficient for junior high school and pre-service physics teacher. However, senior high school students were still relatively weak. The difficulties were found in interpreting formulas and conceptual errors. This research provides practical benefits to the concept of electrical circuits, especially about the low mastery of student’s concepts. The same mistakes at every level of education showed that there are misconceptions that are difficult to eliminate. It is needed to have more effort to master the concept deeply.

Abstract

This research was developmental research with aims to develop, knowing validity and practicability of thermodynamics e-book based on TPACK. This research was using 4D models and did only as far as develop step. The result based on 4D model steps were (1) Define produces task analysis to fulfil 21st century skill, (2) Design produces 2 product which are teacher book and student book, (3) Develop step produces result of validation and the last product (e-book/flipbook for teacher and student). Expert validation showed the teaching instructional material is valid, learning planning is valid, Content Representation is valid, and e-book is valid. 89,5% students responded this e-book very interesting. This e-book can be said quite practically. Limited trial and small experiment were carried out in one of class in senior high school of one Ngoro Mojokerto and concluded that the increase in the stabilization of sub-topic introduction to Temperature and the Thermodynamics Zero Low is high through the activity of comparing (Let’s Compare). Students can learn thermodynamics by keeping up with science and technology developments by this e-book. The practical benefit is helping the success of learning process carried out at school and home because e-books are provided in 2 forms, teacher book and student book.

Abstract

The roasting process has become the most necessary post-harvest handling process to be awarded in controlling coffee quality. In this research, the effect of roasting temperature has been investigated to the chlorogenic acid content on pure robusta coffee of local varieties and its mixture with soybeans as a parameter to control the quality. The temperature of roasting had variated at 195°C, 215°C, 225°C, 230°C, and 240°C. The chlorogenic acid contents have been obtained based on their maximum absorbances measured by a UV-Vis spectrophotometer at 290 nm wavelength range. The increase in roasting temperature reduces the chlorogenic acid levels because some have turned into melanoidin compounds. To increase the weight of Robusta coffee and change the taste of coffee, soybeans have been added as a coffee mixture. The results of the study were then extended to the observation of coffee quality on the content of chlorogenic acid it produces. The addition of soybeans by 10% can increase the chlorogenic acid content at a roasting temperature of 230°C around 5.12%, and there will be a decrease when the temperature is lowered. The addition of soybeans with a mass fraction of 20% of the total amount of coffee has increased the absorbance due to other antioxidant substances from the soybeans. The results of this study are expected to add insight to the public about the temperature required for the roasting process to obtain quality coffee with chlorogenic acid content that is still present after the roasting process.
